Good morning,

Around here, we're using HBase for similar purposes. We have a bunch of
smaller nodes storing the data and all the management nodes(ambari,
HDFS namenodes etc.) are vm's.

Our nodes are configured so that we have a maximum of 2 cores per disk
spindle and 4G of memory for each core. This seems to do the trick and
is pretty responsive.

But to be able to provide better advice, you will probably need to go
into a bit more detail about what types of data you will be storing and
which kind of calculations you want to perform.
